ELEVATOR AND DUMP.

SPECIFICATION forming part of Letters Patent No. 744,767, dated November24, 1903.

r Application filed June 29,1903. Serial No. 163.631. (No model.)

To all 'whom itma y concern:

Be it known that I, JOHN .W. KING, a citizen of the United States,residing at Waitsburg, in the county of Lincoln and State of Washington,have invented a new and useful I Elevator and Dump,'of which thefollowing is a specification. v

This invention relates to that class of dea suitable point of elevationand theredumping the same; and it has for its object to pro .vide adevice of this class which shall be esmachine and there dumped.

A further object of my invention is to construct a device of this classin such a manner as to be extremely simple, inexpensive, and: easilyoperatedand possessed of a great range.

1 points by suitable braces 15 and near their With these ends in viewthe invention consists in the improved construction, arrange ment, andcombination of parts, which will; be hereinafter fully described, 'andparticu-I ries a sprocket-Wheel19, the outer face of of utility.

tor and dump with the carrier elevated and with dotted linesillustrating the dumped po- Fig. 2 is a top plan view. Fig. 3 islaterally-extending arm or bell-crank 24, said sition. a bottom planview ofthe carrier.

Corresponding parts in the several figures; are indicated by similarnumerals of refer-Q above their intersections with'the cross-pieces 3and 4 uprights 7, upon which frame-bars 8 and 8 are mounted abo ve andparallel to the sills 1 and'6 and ofa length'about-equal to therespective lengths" of said -sills. The frame-bars 8, uprights 7,sillsl6, and as much of the sill 1 as is included between the front andrear uprights 7 thus combine to constiextended between the uprights 9.

tute an auxiliary framein which a portion of the operating mechanism ofmy improved elevating and dumping device is mounted.

Suitably supported upon sills 1 and 2 near the rear ends of said sillsare a pair of uprights 9,, connected at their upper ends by a cap-beam10. The track-bars 11 of the device are pivotally connected with thesills 1 and 2 at the front ends of the latter and are The latter areprovided with a plurality of inclined notches 12, in which a cross-baror supporting-rod 13 may be adj ustably supported, said cross-barserving as a support for the inclined track-bars 1 1,'which latter maythus, by adjusting'the position of the bar 13, be adjusted at an ydesired inclination within the capacity of the device. The track-bars'llare provided with flanges 14 for the purpose of guiding the carrier, tobe hereinafter described, and said track bars are" connected atintermediate upper ends by a transverse brace 16.

V The frame-bars 8 support near their rear ends a revoluble shaft 17,carrying a drum 18. A projecting end of said shaft also carwhich isprovided with ratohets 20, forming a clutch member adapted to cooperatewith a clutch member 21, mounted slidably upon the shaft 17, and havingan annular groove 22, engaged by a forked lever 23, having a lever,comprising the members 23 and 24, being suitably fulcrumed tothe frameof the machine. Pivotallyconnected with the lever-arm 24 is anoperating-rod 25, which extends through a suitably-disposed guide 26 ina forward direction to'apoint at which it may be convenientlymanipulated by the op erator to throw the clutch members 20 and 21 intoor out of engagement. It is obvious that the combined clutch member andsprocket wheel is normally loose upon the shaft 17, with which it may beoperatively connected by means of the slidable clutch member 21, thelatter being connected rotatively with the shaft 17 by means of a fin orspline or in any other suitable well-known manner. 4

27 designates a shaft which is supported revolubly in boxes 28 upon theunder sides of the frame-bars S and 8, and said shaft carries aratchet-wheel 29 and a sprocket-wheel 30, which latter is connected by achain 31 with the sprocket-wheel 19 upon the shaft 17. Adjacent to thesides of the ratchet-wheel 29 are a pair of arms 32, which are mountedpivotally upon the shaft 27, and each of these arms carries a pawl 33,engaging the ratchetface of the wheel 29. 4 These pawls may be weightedorspring-actuated in order that they may be held operatively inengagement with the ratchet-wheel.

34 designates an operating-lever fulcrumed at 35, and 36 36 are a pairof connecting-rods pivotally connected with the operating-lever 34,equidistantly from and at opposite sides of the fulcrum 35, the outerends of said conmeeting-rods being pivotally connected with thepawl-carrying arms 32.

A wheeled carrier 37, the detailed construction of which will bepresently more fully described, is adapted to run upon the inclinedtrackbars 11, connected by the brace 16,whichlattersupportsaguiding-pnlley 38,0ver which passes thehoisting-rope 39, one end of which is made fast to the carrier 37 andthe opposite end of which is connected with the drum 18.

It will be seen that when the operating-lever 34 is manipulated the pawlcarrying arms 32 will be alternately reciprocated in oppositedirections, thus imparting to the ratchet-wheel upon the shaft 27 arotary motion, as will be readily understood, one of the pawls33slipping over the teeth of the ratchet, while the other pawlsimultaneouslypropels the ratchet-wheel in the proper direction. Rotarymotionisthusimpartedtothesprocketwheel 30, from whence it is transmittedby the chain 31 to the sprocket-wheel 19, which is supposed to be inoperative engagement with the clutch member 21. The shaft 17, carryingthe drum 18, being thus revolved, the hoisting-rope will be wound uponthe drum, thus causing the carrier 37 to travel in an upward directionupon the inclined track, which, as previously described, has beenadjusted at the desired inclination. After the carrier has reached theproper elevation and been tripped, as will be hereinafter described, theoperating-rod 26 is manipulated by the operator to disengage the clutchmembers 20 and 21, when the drum-carrying shaft will be rotated tounwind the hoisting-rope from the drum by the descent of the carrier,which is accomplished by the weight of the latter.

The carrier 37 may be described as consisting of suitably spaced andconnected side pieces 40, having wheels 41 and provided with across-piece 42, pivotally mounted between the side pieces of saidcarrier and supporting a dumping-board 43. It should be observed thatthe pivoted cross piece 42 should be disposed comparatively near thelower end of the carrier-frame, so that approximately two-thirds of thedumping-board shall be disposed above the pivotal point in order thatthe weight of material placed upon said dumping-board shall besufficient to tilt the latter at the point of discharge. Thedumping-board is provided at its lower end with a cleat 44, affording arest for the material placed thereon, such as a sack of grain, and ithas a downwardly-extending slotted catch 45, adapted to be engaged byaspring-actuated latch 46, which is mounted upon the under side of thecarrier-frame. downward-extending spur 47, which is adapted to beengaged bya trip 48, suitably disposed upon one of theinclinedtrack-beams 11. The operation of this part of my invention will bereadily understood. When the carrier is at the lower end of the track,the material to be elevated, which, as stated, is usually in the form ofgrain in sacks, is placed thereon, displacement being prevented by thecleats 44. The carrier is then elevated upon the track in the mannerdescribed until it reaches the upper end or discharge-point, where thespur 47 of the latch 46 is engaged by the trip 48, thereby disengagingthe latch from they catch 45, and thus causing the dumping-board to betilted by reason of the excess of weight above the pivotal point of thedumping-board. As soon as the latter is relieved of its weight the rod26 is manipulated by the operator to disengage the clutch members 20 and21, thus permitting the carrier to descend by its own weight, the latchmechanism becoming automatically locked when the dumping-board isrestored to its normal position by its passage over the cross bar orbrace 16.

I desire it to be understood that while I- have in the foregoingdescribed a simple and preferred construction of my improved elevatingand dumping devicel do not necessarily limit myself with regard to thestructural details herein set forth, but reserve the right to anychanges, alterations, and modifications which may be resorted to withoutdeparting from the spirit or scope of my invention and withoutsacrificing the utility of the same.
